2 Sheets-Sheet 2 Filed Jan. 21. 1931 Patented Dec. 19, 1933 UNITED {STATES PATENT OFFICE r '7 Claims.

This invention relates to water closets provided for use in railway cars and like'locations and while it will be hereinafter described as embodied in a water closet like those shownin the co-pending applications of John C. Duner for United States Letters Patent, Serial Numbers 375,242

and 375,243, filed July 1, 1929,.it will be readily apparent that from certain aspects the invention has broader and more general application.

Toilets of this sort are ordinarily provided with a dump pan adapted to be dumped in flushing with a resultant upiiow of air frequently occurring with considerable velocity and producing a blast directed upwardly through the toilet or closet.

In the co-pending applications above referred to, a draft member is disclosed for sealing the closet outlet as an incident to the flushing of the toilet. This draft member, preferably and in accordance with the disclosure of said pending applications, moves into sealing or closed position during the initial opening movement of the dump pan and prior to the breaking offthe water seal.

Theinstant invention has for its principal object the improvement of the dump pan and draft member operating mechanism.

The invention contemplates the provision of an improved'operating mechanism of the character described which will be of simple construction, easy manipulation, and produce quick closing of the draft member during the initial opening movement of the dump pan, the parts being preferably so constructed and arranged F that the draft member comes to a final sealing position prior to the breaking of the water seal in the dump pan.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

Figure 1 is a side elevation of a'water closet embodying the present invention, parts being broken away and shown in section to disclose internal features of construction; and

Fig. 2 is a front view similarly taken.

50 The water closet embodying the present invention shown on the drawings comprises a metal stand 11 and a ceramic bowl 12 supported in the stand above its outlet 13. A dump pan generally indicated at 14 is fixed upon a pivot shaft 15 having a bearing in the stand 11 to swing Cab A draft member 24 is pivoted at each side at 25 in the lower part of the stand 11 and is adapted to be moved to seal thecloset outlet 26. An arm 27 is fixed to one'of the pivot or stub shafts 25 of the draft member and is provided with a pin 28 loosely mounted in the lower slotted end 29 of an arm 31 arranged loosely on the pivot shaft 15 of the dump pan.

The arm 31 is provided with a projection or lug 32 adapted to bear against and engage the arm 19 'on the pivot shaft 15. A second arm 33, is also fixed uponthe pivot shaft 15 and this arm is connected by a coil spring 34 with .an arm. 35 formed integral with the arm 31.

A weight 36 is or may be provided also upon the pivot shaft 15 to return the dump pan and draft member to normal positions after flushing of the toilet.

Thus constructed and arranged, lifting of the lever 17 causes the shaft 15 to be oscillated to swing the dump pan downwardly. As an incident to the initial opening movement of the dump pan, the arm 31 being held against the arm 19 by the spring 34, swings the arm 27 in a counter clockwise direction (viewing Fig. 1) to close the draft member. The arrangement of the parts is such that the closing of the draft member is quickly accomplished and the dumping movement of the dump pan continues with corresponding elongation or stretching of the spring 34. The dumping movement of the dump pan is accomplished. by a raising of the weight 36 and upon the release of the lever, the weight causes a reverse or return movement of the parts, the sealing of the draft member continuing until the dump pan is back to or substantially back to its normal original position.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form,

.construction and arrangement of 'the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A water closet, comprising a closet bowl supported above its outlet, a dump pan positioned beneath said bowl and adapted to swing from a sealing position downwardly to a dumping position, a draft member located beneath said dump pan and arrangeable in sealing position as an incident to the dumping of said dump pan, a shaft rotatable with said dump pan in its movement, a fixed operating arm on said shaft, a loose draft member operating arm on said shaft, and yielding means connecting said arms. 7

2. A water closet, comprising a closet, bowl supported above its outlet, a dump pan positioned beneath said bowl and adapted to swing from a sealing position downwardly to a dumping position, a draft member located beneath said dump pan and arrangeable in sealing position as an incident to the dumping of said dump pan, a shaft rotatable with said dump pan in its movement, a fixed operating arm on said shaft, a loose draft member operating arm on said shaft and a spring causing said draft member arm to follow the movement of said operating arm until said draft member is closed.

3. A Water closet, comprising a closet bowl supported above its outlet, a dump pan positioned beneath said bowl and swinging from receiving to dumping'position, a draft member positioned beneath said dump pan and arrangeable in sealing position as an incident to the dumping of saiddump pan, and a resilient connection between said dump pan and said draft member for imparting simultaneous initial opening movement to said dump pan and draft member.

ing movement to said dump pan and draft member, said connection moving said draft member into fully closed position during the initial opening movement of the dump pan.

5. A water closet, comprising a closet bowl supported above its outlet, a dump pan positioned beneath said bowl and swinging from receiving to dumping position, a draft member positioned beneath said dump pan and arrangeable in sealing position as an incident to the dumping of said dump pan, and operating means for said dump pan and said draft member imparting a faster initial movement to said draft member than said dump pan, and yieldable during continued opening movement of the dump pan after the draft member comes to rest in closed position.

6. A water closet comprising a closet bowl supported at its outlet, a dump pan positioned beneath said bowl and swinging from receiving to dumping position, a draft member positioned beneath said dump pan and arrangeable in sealing position as an incident to the dumping of said dump pan, a yielding'connection between said dump pan and said draft member for imparting simultaneous initial opening movement to said dump pan and draft member, said connection moving said draft member to fully closed position during opening movement of said dump pan, and manipulative means unyieldingly swinging said dump pan to its open position.

7. A water closet comprisisng a closet bowl supported above its outlet, a dump pan positioned beneath said bowl and swinging from receiving to dumping position, a draft member positioned beneath said dump pan and arrangeable in sealing position as an incident to the dumping of said dump pan, a linkage connection between said dump pan and draft member, a manipulative device engaging a link of said connection secured for movement with said dump pan, and yielding means associated with said linkage connection and causing said draft member to move to closed position during the initial movement of said dump pan.
